Data sources

Most of the data on this page comes from the Human Fertility Database (website www.humanfertility.org (data downloaded on December 2, 2013, last updated August 8, 2012). The data collected by the Human Fertility Database is based on government data collection by the government of Japan. Details about the modalities of data collection are available here.

Data on period fertility

Data of total indicators only without breakdown by birth order

Year CBR (births per 1000 people per year) CBR minus previous year's CBR TFR (sum of all age-specific fertility rates), ballpark for replacement fertility is 2.1 TFR minus previous year's TFR TFR40 (sum of age-specific fertility rates up to the age of 40), almost equal to TFR because births above the age of 40 are rare TFR40 minus previous year's TFR40

Data on completed fertility

This data is from the Human Fertility Database. Max Planck Institute for Demographic Research (Germany) and Vienna Institute of Demography (Austria). Available at www.humanfertility.org (data downloaded on December 2, 2013, last updated August 8, 2012).

The CCF column denotes the completed fertility rate for the birth cohort born in that particular year, and the CCF40 denotes the parity at age 40 for the birth cohort born in that particular year. CCF40 values cannot be available for birth cohorts born less than 40 years ago, whereas CCF values cannot be available for birth cohorts born less than 49 years ago.

Cohort CCF CCF40 CCF1 (proportion that have a first birth) CCF2 (proportion that have a second birth) CCF3 (proportion that have a third birth) CCF4 CCF5+ (sum of CCF5 and higher values)
